SPECIFCATION forming part of Letters Patent No. 422,320, dated February25, 1890.

Application filed October 12, 1889.

:To all whom, it may concern.-

Beit known that we, HENRY V. SCATTER- eooD and CHARLES F. SoAT'rEEeooD,both of the city and county of Albany, in the State of New York, haveinvented new and useful Improvements in Ealing-Presses, of which thefollowing is a full and exact description, reference being had to theaccompanying drawings, which form part of this specification, and inwhich- Figure 1 is a side elevation of our press. Fig. 2 is a plan view,showing the toggle-joint of the plunger-'operating mechanism at theopposite side of the press from the position in which it is shown inFig. 1. Fig. 3 is a longitudinal section of Fig. 2 at the line X X. Fig.4 is a horizontal section, taken at the irregular line Y Y on Fig. l,but with the plunger at the extremity of its inward stroke and itsoperating mechanism in a corresponding position. Fig. 5 is a perspectiveview of one vof the division-blocks for separating thebales.

Fig. 6 'is an enlarged and detached side elevation of the upper portionof one of the shafts for our automatic locking device; and Figs. 7 and'Sare enlarged and detached planvviews of the locking arms and detents forautomatically stopping the outward movement of a division-block, saidfigures, respectively, showing a locking-arm in a protruded and an in'-truded position. f 1

Our vinvention relates to improvements on that class of baling-pressesin which advantage is taken of vthe resilient power of the compressedmaterial to effect the outward stroke of the plunger of the press, andin which the toggle-joint of the plunger-operating mechanism is notcontinuously connected with the sweep, to which the animal-power isattached, for the purpose of operating the press; and our inventionconsists of the novel construction and combination of parts herein shownand described, and particularly pointed outin our claims.

As represented in the drawings, A designates the frame-work or body ofour press, said frame-Work being made in the usual form of suchstructures, excepting in those parts which are changed to suit thespecially-de signed features of our-invention.

B is a stationary shaft-like bar, whiehis se- Serial No. 326,802. (Nomodel.)

cured in a fixed position in the bosses of the cross-ties l by means ofcross-pins 2 or other suitable fastenings. Said shaft-like bar isprovided with a lcrank-like bend C, whose throw is permanently turnedtoward the baling-chamber of the press, and the fixed pivot 3 of saidcrank-like bend forms the center on which the sweep D swings to operatethe plunger-operating mechanism. The body of 6o the shaft-like bar B,both above and below the crank-like bend C, forms centers for theswinging cranks E, which form portions of the toggle-levers foroperating the plunger of the press. The hubs 4 of said cranks fit 65loosely upon the body of the shaft-like bar B, so that said cranks willswing freely thereon, and the opposite end of each crank is providedwith an eye 5, in which a wrist-pin 6 is secured, so as to form thecenters for the outer 7o ends of the pitmen F. Said pitmen, inconjunction with the swinging cranks E, form the toggle-levers by whichthe plunger of the press is forced inwardly. An anti-friction roller 7is loosely fitted to revolve on the 75 wrist-pin 6, so as to receive thethrust of the sweep of the press in a comparatively frictionless manner.The opposite end of the pitman Fis jointed by a pin 8 to the plunger G,the latter being preferably made of metal, 8o and also preferably in theform of an opensided box, whose head Q forms lthe pressingsurface ofsaid plunger,whose lower plate is provided with rollers l0, to reducethe friction of said plunger in its reciprocations in the press, andwhose upper plate is provided with a stud or hook ll, for a purposehereinafter explained.

D is the sweep of the press or the lever to which the animal-power foroperating the 9o press is applied. Said sweep is preferably made in theform of an A-frame composed of two side pieces l2, which are joinedtogether at the outer ends, their inner ends being fitted to entersockets or seats in a yoke I` 95 The latter contains a eentrally-locatedU- shaped opening, which is provided with a binder 13, so as to form abearing or journalbox which lits the fixed pivot 43, so as to allow thesweep D to swing freely thereon. The roo face of the yoke I has a convexswell 14, that corresponds to the journal thereof on said fixed pivotand its flanks 15, which extend in a straight line directly from theopposite sides of said convex portion, said line being in effect astraight line which radiates from and passes through the center of thefixed pivot 3. Said flanks are fitted to bear successively against theanti-friction roller 7 on the wrist-pin of the swinging cranks E, so asto impart the required movements to the tog- Io gle-joints for effectingthe inward strokes of the plunger.

It will be noted that the yoke I has no permanent connection with thetoggle-joint, but only operates the latter while in contact there with,and it will also be noted that the pivotal centers for the swingingcranks E and for the sweep D are formed by a single piece of the formhereinbcfore described, thereby combining extreme strength with greatsim? zo plicity of construction, and so that said centers are fixed atdifferent points, on the cenr tei-line of the press, whereby theleverage of said sweep is rendered constantly variable, and will beleast when said cranks are at the 2 5 extremity of their outwardmovement at either side, one of said positions .being shown in Fig. 2,in which the uppermost crossftie 1 is partially broken away to moreclearly show the position of said cranks, and the greatest 3o leverageof said sweep will be attained when the friction-roller 7 is carriedclosely by the convex swell 14, so that the center lines of the swingingcranks and pitmen will range in a direct line, as shown in Fig. 4., atwhich 3 5 point the plunger G will be at the extremity of its inwardstroke. Vhen the swinging cranks E are at the extremity of their outermovement on either side of the center line of the press, the eyes 5 ofsaid cranks will come 4o in contact with stops 1G, formed on thecrossties 1, whereby the movement of said cranksk will be terminated,and when the plunger G has nearly reached the extremity of its ontwardstroke it comes in contact with a spring 17', which gradually retardsits movement and prevents the eyes of the swinging cranks from strikingtoo heavily against the stops 16.

J is a cross-head that is fitted to slide in `the guides K, which arepivoted, as at 18, to 5o the frame-work of the press, so that saidguides can be swung upward, as indicated by dotted lines in Fig. 3, whenoccasion requires. Said cross-head is connected by springs 17 to theframe-work of the press eontiguously to the shaft so as to normally drawthe cross-head in that direction. Said cross-head is fitted to engagewith the stud 11 of the plunger G when the latter is near vthetermination of its inward stroke, and the 6o continued movement of saidplunger will cause the springs 17 to be elongated, so that when theplunger is freed from the control of the togglc-levers, the resilienceof the springs will vaid in effecting the rebounding move- 6 5 ment ofsaid plunger toward the power end of the press.

By raising the cross-head J to the position indicated by dotted lines inFig. 3 it will be carried out of the path of the stud 11, and therebounding movement of the plunger G will then be effected by theresilience of the compressed material.

When preferred, the cross-head J may be dispensed with and the springs17 may then be secured directly to the plunger and to the frame-work ofthe press, so that they will at all times aid in producing therebounding movement of the plunger.

L designates spring-actuated retainers whose points enter the sides ofthe press and extend into the baling-chamber M, to prevent thesuccessive charges of the material which have become compressed fromfollowing' the plunger on itsoutward strokes.

N is a folder,- which is located at the chargingend of the balingchamberM, and secured to the upper side of the frame-.work A by the spring 19.The lower face of said fold er is beveled upwardly toward thecharging-opening O," and thepurpose of said folder is to fold down anyloose parts of the material at the upper side of that end of a bale aseach successive charge is forced intothe balingeha,mber.

P are dogs or detents which are fitted opposi tely in the vertical wallsof the press, near the discharging end of the baling-chamber M, saiddogs being fitted to slide laterally into said baling-chalnber for thepurpose of holdingin positiomto forma stationary head against which thebales are compressed, one of the movable division-blocks Qwhich sepa-`rate the bales from each other in the operation of forming the same.lSaid dogs areconneeted by links 20to arms 21, which are on the verticalshafts R, that are journaled to the outer side of the frame-work.,adjacent to the discharging end of the baling-chamber. The lower end ofeach shaft R, is provided with an arm 22, which connects with aspring'23, whose opposite endv is. attached to a` fixed point on theframeswork A, and the effect lof said springs is to rock the shafts R,when the latter are left free to move, seas to` throw the dogs Pinwardly into the position shown in Fig. 4. To the upperend of eachshaft R a lever 24 is looselyiitted', so that the shaft can be turnedfreely in the hub of the lever, each of said levers being connected by aspring 25 to the upper side of the press, and the hub of each leverbeing provided with a slot 26, through which projects ay pin 27, whichis secured to the shaft. Said levers nominally remainin; the positionshown in Fig. 2, Where the pin 27 will be at the end of the slot 26, toeffect the turning of the shaft to retract the dogs Pinto the positionshown in Fig. 2, and when this retraction has been accomplished thelevers will return. to their normal position.

S designates locking-arms, which are provided with slots 28, throughwhich pivot-pins 29 pass, so that each of said arms can have both aswinglng and a sliding movement as occasion may require. A tail-piece30, formed on the forward end of each of said lockingarms, is fitted tostrike against the side of the plate to which said arm is pivoted, and

thereby the opposite end of the latter is pre-V vented from swinging outtoo far, and'each of said arms is provided with a spring 31, which hasone end attached to the frame-work of the baling-ehainber M, and a heel33 is also formed on each of said arms to extend outwardly. Said toe isfit-ted to enter pockets 34, formed in the opposite edges ofthedivisionblocks Qwhen the latter have nearly reached a position at thedischarge end of the balingchamber to serve as ahead against which abale can bev compressed, at which point the locking-arms S willswinginwardly, their toes 32 entering the pockets of the division-blockssoas to release the vdogs P, which are forced inwardly'by the action ofthe springs 23, in the manner presently described, in time to debar thefurther outward movement of said Y divisionblock,'at which time thedivisionblock and the locking mechanisms will be in the positions shownin Fig. 8. While a com-` pressed bail is still in the baling-chamber Mand after said bail has been tied off, the divisioni block can bereleased from the hold of thedogs P, and this is effected by turning theshafts R by means of the levers 24, so as toretract said dogs into theposition shown 4in Fig. 7, andas soon as this retraction occurs theresilience of theeompressed matel`rial will cause the bale to expandlengthwise to the limit of the ties around it, and by this *outer sidesof the bale.

expansion the division-block will be ejected f rom the open end of thebaling-chamber, and

the compressed material, by closing over the openings through which thetoes k32 enter the balingphamber, will prevent said toes from enteringsaid chamber. After the toes 32 enter the openings 34 in thedivision-block Q the pressure applied to the material in the press willcause said division-block to move toward the discharge end of the pressuntil its further movement is arrested by the dogs P, and in making thislastnamed movement the plate on the innermost side of the openings 34will be brought to bear against the convex edge of the toes 32, wherebythe lock ing-arms S will be forced to swing outwardly, seas to bring thetoes 32 to bear against the Then on4 turning the shafts R` to effect aretraction of the dogs P Ythe arms 21 will iirst engage with theadjacent edge of the heels 33 to push the lockingarms S endwise untilthe arms 2l are carried beyond the outer end of the heels 33, and

the arms 21 will bear against the outer end of said heels, so as toretain the ends of the toes 32 in contact with the sides of the bale inthe baling-chatnber until the next divisionblock is carried intoposition to release said locking-arms and dogs in the mannerhereinbefore described.

With the understanding that the sweep D swings from onevside of thepress to the op-A posite side, the crank-pin ofthe crank C forming itspivotal center, and that a divisionblock is inserted through thecharging-openin g O to rlie at the charging end of the balingchamber Mjust before the beginning of the formation of each bale, the operationof our press will be understood from the following statement: While theplunger E is at the outer extremity of its stroke, as shown in Fig. 3,the swinging cranks E being in a corresponding position at either sideof the center line of the press, a charge of material is fed into thecharging-opening O and the sweep D is moved in the direction required toforce'the plunger G inwardly. At the beginning of said movement of thesweep the friction-roller 7 will bear against the yoke 1,

n near one of the extremities of the latter, where the sweep will exertits least leverage, the resistance of the material being then at aminimum. By the continued movement of the sweep the friction-roller 7will be carried nearer the middle of the yoke 1, and thereby theleverage exerted by said sweep will be constantly increased until thecenter lines of the swinging cranks E and pitmen F range ina directline, and at that point the leverage of the sweep will reach the maximumand the plunger G will be at the innermost extremity of its stroke. Atthis point there occurs a slight cessation in the movement of theplunger, while the friction-roller is in contact with the convex surfaceof the swell 14, and after passing this point the plunger will reboundby the resilient action of the springs 17, or of the compressedmaterial, whereby the plunger will be returned to the outer extremity ofits stroke with the toggle-joint in ofthe press. These operations arecontinued until a'bale of the required size has been formed. Thenanotherdivision-blockis forced into the baling-chamber M, and isheld'therein by the spring-retainers L until the ties are passed aroundthe bale and fastened thereon.

Then the shaftsR are partially rotated to draw back the dogs P, so as torelease the divisionblockthat has been serving as a head to compress thebale against, whereupon the endwise expansion of the compressed balewill forcibly eject said division-block from the open discharge end ofthe baling-chamber M. The endwise expansion of the compressed balecauses the compressed material at the sides ofthe bale to cover theopenings in the sides ofthe baling-chamber, through which'the 4vtoes ofthe locking-arms S intrude, and there ICO IIO

a corresponding position at the opposite side by the latter areprevented from swinging inwardly to release the dogs P until a new bale,now in the process of formation, has pushed the finished bale far enoughout of the dis charge end of the baling-chamber to allow a succeedingdivision-block Q to reach a position where its pockets 34 will be readyto rcceive the toes 32 of the locking-arms. lVhen this point is reached,the springs 23 will cause the shafts R to make a partial rotation toforce said locking-arms to swing inwardly, thereby carrying the toes 32into the pockets 34, freeing the arms 2l from the heels of thelockingarms S, thereby effecting aforcible movement of the dogs Pinwardly to debar the further movement of the divisionblock Q, whichthen becomes a stationary head to receivek :and resist the pressureapplied to the material in the bale. The finished bale,whichprotrudes'from the open end of the baling-chamber M, is removedtherefrom by hand in time to allow the free escape of a division-blockwhen the latter is ejected by the expansion of the next succeeding bale.

XVe are aware that Letters Patent No. 408,115 covers a constructionwhich comprises the combination of a reciprocating plunger,atoggle-joint having one end jointed to said plunger and the other endjointed to a fixed pivot, and a sweep fulcrumed on a fixed pivot locatedbetween the pivot for the toggle-joint and the reciprocating plunger,said sweep being provided with a head having at each end a finger orhorn, which extendstoward the plunger, the points of said fingers vbeingfitted to take against the knuckle of the toggle-joint before Contact ismade between said knuckle and any other part of said head; but we do notclaim such a construction, as it is open to many objections; but
